My nephew Joie Foust. Works for a company that takes care of our militarys aircraft. They take apart the Blackhawk helecopters and clean all the sand from the wires, and other engine sand removel. The constan rubbing of the sand will ruin the aircraft. I am very proud of him. Besides a very hard working man, he has a spirt that is infectious to anyone hes around. Plainly "A great human"
